Be it known' thatl I, O'T'T'QIMILLER, a'citizen of the United States, residing at Glenellyn, in the county of Dupage and State of Illinois', have invented vcertain new and useful Improvements'in Valve V'Mechanism for EX- plosive-Engines,v of'which the following is a speciiication.

`My invention relates to valve mechanisms for use in connection with internal combustion engines, for controlling the inlet or exhaust of gase's into.. or out of the cylinders:

of the same and has particular reference to 'mechanisms of this character embodying a hollow cylindrical double walled rocker valve which is maintainedproperly cooled by the continuous circulation of oil between the inner and outer walls thereof, such oil also serving-tol thoroughly lubricate the dif- 'ferent working-parts ofI the mechanism.

An importantobjectof this invention is to 'provide mechanism of the above mentioned applied, and, Fig. 2 is a sectional view'taken' on line 2-*2 of Fig. 1.

In the drawings, wherein is illustrated a preferred embodiment of my invention, the numeral 3 designates a cylinder, provided at its upper end with gas pipes or ports 4 and 5. Mounted to reciprocate within the. cylinder 3 is a piston 6, pivotally connected with a pitman 7. Thispitman is connected with a crank 8 driving a pinion 9 which in turn drives anions. 10.

Surrounding the upper portion of the cylinder 3 is a jacket 11, forming a water space l2, as shown. The water is preferably introduced into the lower end of' the jacket 12 at an opening 13 and discharge from the upper end thereof through an opening 14. Suitably mounted within the upper portion of the jacket 12 are inlet and exhaust valve mechanisms 15 and 16. As these valve mechanisms are identical, it is thought that a Speclimatica-.01!

horizontal stationary shell or casing 17,4 provided with an outer pipe or port 18 andan inner port or opening' 19 for receiving-the gas pipe 4, as shown. An oil supply pipe 2O leads into the lower portion of the stationary casing 17 as shown at 21, such oil discharging fromy the upper portion of the stationary casing 17 through an outlet oil pipe 22. A pump, (not shown) which maybe preferably'located `mithin the crank case, is em-y ployed to continuously circulate the oil through the pipes 20 and 22. Disposed within -the outer stationary shell 17 is a cylindrical outer` valve casing 2 3 adapted to turn or rock therein. Y This outer valve. casing 23 is provided Y with relatively large openings or ports 24 and 25, which-main tain the oil plpes 20 and 22 permanently u ncovered to permit of the continuous flow of the oil int'o and out of the outer casing 17, while the valve mechanism is operating. Disposed within the outer valve casing 23 is an innervalve casing 26, which is smaller'in diameter and concentrically arranged with relation thereto, for providing an annular oil circulating chamber 27, as shown. The inner valve casing 26 is provided with an outer gas pipe or port 28, passing through an opening in the outer valve casing 23, and adapted for movement into and out of registration With the outer pipe or ort 18. The inner valve casing 26 is furt 1er provided with an inner gas pip'e 29, passing through an opening in the outer valve casing 23 and -adapted to be moved into and out of registra` tion with the cylinder pipe 4. The pip'es 28 and 29 serve to rigidly connect the inner 23 to retain the salne'suitably spaced therefrom. Other spacing means may be employed if necessary. As more clearly shown in Fig. 2, the ends of the inner valve casing the ends of tbe outer valve casing 23. It is thus seen that lprovidea double walled hollow v'alve, for controlling the inlet of the gases into thecylinder 3, such double walled hollow valve being provided in its outer wall with relatively large oil openings, whereby annular oil circulating chamber of the same, thus keeping the different parts of the valve properly cooled, and lubricated. The outer valve casing 423 is provided upon its outer surface with grooves (not shown) whereby the oil engaging the inner surface of the staa J26 carry spacing elements 30, which engage valve casino 26 with the outer valve casino' the oil is continuously circulated through the i tionary casing 17 may-more readily pass between the same and the outer valve 23.

Connected with each of the outer" valve casings 23 is a crank 31, which turns orrocks the same. This'crank has pivotal connection with a reciprocatory rod 32, operating through a stationary housing 33. The reciprocatory rod 32 is formed of two hinged sections, so that it will not bind, due to the swinging movement of the crank 31., The rod 32 is forced downwardly bya compres sible coil spring 34, Aand carries at its lower end a roller 35, which is engaged' by a `cam 36, rigidly connected with the gear wheel 10.

The operationof the valve mechanism Al5 is as follows: The oil is supplied through the inlet pipe 20, passes into the oil circu. lating chamber, and discharges through the' This oil coolsthe double outlet pipe 22. walled hollowvalve and also lubricatesvthe engaging surface ofthe casings 17 and-23.

The ports 24 and .25 permanently maintain the pipes- 2O and 22 uncovered, whereby the circulation ofthe oil through the chamber 27 is continuous. The gas passes through the pipe 18, through pipe '28, into the innei` valve easing 26, through vpipe 29, andp ipe 4 into the cylinder 3,

The operation of the exhaust valve mechanism 16 is as follows: 'The gaseslfpass from the cylinder 3, throgh pipgpipe 29, the

inner valve c'asin'g" 26, pip 28, pipe 18 to the atmosphere. -Tlielubrication is thesame as described in connection with the valve mechanism l5.

It is. to-be understood that the form of my invention herewith shown and described is to be taken as a preferred exampleof the same, and that certain changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope 'of the subjoined claims. 1 f
